APP程序远程更新GITHUB RELEASE
要自己架设一个服务器来提供app更新，别说是配置服务器了，光是买个主机都很棘手。但是github提供了release功能，并有相关api支持。下面介绍如何使用github的release功能。
这里以DTU802 基于.net开发的iotgateway程序为例，硬件，软件界面如下：
在guthub上新建工程，创建release：
出现如下界面，上传文件和填写信息：
勾选了Pre-release,后API提示错误：
{
“message” : "Not Found",
"documentation_url" : "https://xxx"
}
Publish Release:
通过github官方提供的api可访问我们的release信息：
/repos/:owner/:repo/releases/:id
例如：我的release的api是
https://api.github.com/repos/peixiuhui/IOTGate/releases/latest 获得最新版本号： wget -qO- -t1 -T2 "https://api.github.com/repos/peixiuhui/IOTGate/releases/latest" | grep "tag_name" | head -n 1 | awk -F ":" '{print $2}' | sed 's/\\"//g;s/,//g;s/ //g'
执行如下：
huiwei@hwserver:Code$ wget -qO- -t1 -T2 "https://api.github.com/repos/peixiuhui/IOTGate/releases/latest"

V20
huiwei@hwserver:Code$
这样就获取到软件的版本号为V20了，也可通过解析这个Json数据获取版本信息，从而 实现 软件是否需要更新。
需要更新的话，将固件下载到本地==> md5校验，校验硬件型号，替换，等等... Go ...
